Network Configuration Management Method, Network Band Management Method, Network Participation Method, and Communication Terminal Device

Abstract

A network configuration management includes the steps of sending from the management terminal (1100) participation terminal information stored in the management terminal; receiving by the participation terminal (1200, 1300, 1400) other than the management terminal, participation terminal information sent from the management terminal (1100); judging by the participation terminal other than the management terminal, whether or not the participation terminal can communicate with another participation terminal device that is participating in a wireless network (1010); sending a communication availability judgment result which is obtained by the judging step, from the participation terminal other than the management terminal to the management terminal (1100); and determining by the management terminal (1100), a participation terminal that should be excluded from the wireless network (1010) in accordance with the communication availability judgment result, and deleting by the management terminal device, from the participation terminal information the participation terminal that should be excluded from the wireless network (1010), thereby updating the participation terminal information which is stored in the management terminal.

Description

TECHNICAL FIELD[0001]The present invention relates to a method of managing a configuration of a network which is constructed so that a plurality of communication terminal devices (hereinafter also referred to as a “communication terminal” or “terminal”) can directly communicate with each other, a method of managing a communication band in a network, a method of participating in a network, and a communication terminal device which forms a network.BACKGROUND ART[0002]Recently, wireless networks are widely used in offices and homes because of their merits that they are free from troublesome wiring in wired networks and that their layouts can be flexibly changed. For constructing a wireless network, there are two types of method: in one method, an access point is used and terminals always communicate with each other via the access point, and in the other method, no access point is used and terminals directly communicate with each other.[0003]In a method using the access point, the termi...

AI Technical Summary

Benefits of technology

[0022]In a network configured according to the present invention, there is an advantage that communication reachability between the communication terminals that are participating in the network can be continuously ensured, even if the communication condition changes.

[0023]Further, according to the present invention, a communication band can be appropriately managed, even if a transmission rate changes. Furthermore, since a network is configured so that the communication terminals can directly communicate with each other without an access point, there is another advantage that the communication band can be used twice as much as that in a network using an access point for communication.

[0024]Moreover, according to the present invention, if the present invention includes the steps of: receiving participation terminal information of the communication terminal that is participating in the network, the participation terminal information being sent from the management terminal at regular intervals; judging communication availability judgment indicating whether communication with the communication terminals that are participating in the network can be performed and available transmission rates, in accordance with the participation terminal information; sending a participation request which contains a result of the transmission rate judgment to the management terminal; receiving a participation permissibility judgment result indicating whether the participation requesting terminal can participate in the network or not, the participation permissibility judgment result being sent from the management terminal, as a result of the participation request sending; and determining network participation permissibility in accordance with the received participation permissibility judgment result, there is another advantage that a network can be realized in which all the terminals that are participating in the network can directly communicate with each other without an access point, the terminals can acquire available transmission rates for communication between the terminals, and the transmission rate of a predetermined or better communication quality can be maintained, in comparison with a network communication reachability ensuring method.

[0025]Furthermore, there is another advantage that communication can be efficiently performed by acquiring available transmission rates for communication between terminals. For example, when a terminal performs broadcast communication, in a network which ensures only communication reachability, the communication can be performed only at a transmission rate or less whose communication availability is confirmed. On the other hand, in a network of the present invention, a terminal can communicate with all terminals in the network by using the maximum available transmission rate at the time. Accordingly, data transmission using a low transmission rate can be reduced and the network can be efficiently used.

Problems solved by technology

However, in order to construct a wireless network by using a method with the access point, the access point is always required, and the terminals cannot communicate with each other if there is no access point.

However, whereas in the method using the access point, all the terminals can communicate with each other if each of the terminals can communicate with the access point, in the method that the terminals directly communicate with each other, the communication in the network is not be ensured if the terminals cannot directly communicate with each other.
